Background
Clinical Features
- Dyspnea, CP, syncope
- Once symptoms present mean surival is 2-3yr
- ejection systolic murmur radiating to carotids
- Pulsus parvus et tardus, slow to rise and late peaking
- Narrowed pulse pressure
- Soft 2nd heart sound
Diagnosis
- Echocardiography, transthoracic. This will typically demonstrate minimal excursion of the aortic valve leaflet. Continuous wave doppler across the aortic valve with typically demonstrate high velocities. Color doppler will demonstrate turbulent flow across the valve. The left ventricle will demonstrate left ventricular hypertrophy.
Differential Diagnosis
Valvular Emergencies
Treatment
- Admission
- Avoid BBs, CCBs
- Afterload reduction is controversial
- Consider cards consult
- AS + A-fib = emergency
- Consider emergent cardioversion
- Pulm edema
- Diuretics, intubation if necessary
- Extreme caution with use of nitrates/vasodilators
